The Neonatal Palliative Care Attitude Scale: Psychometric properties for Portuguese neonatal nurses

This study is aimed to perform the translation and cultural adaptation of the Neonatal Palliative Care Attitude Scale (NiPCAS) and evaluation of its psychometric properties with Portuguese neonatal nurses. The research started with a scoping review that allowed the identification of the NiPCAS. It was a methodological study with a quantitative approach. The semantic equivalence of the items was adjusted with the participation of 20 neonatal nurse experts. They performed facial and quantitative content validation. Psychometric validation of the NiPCAS was performed on a nonprobability nurses sample ( = 283) in 13 level 3 neonatal units between July 2021 and February 2022. Confirmatory factor analysis using the polychoric correlation matrix was performed to estimate factor validity using the "lavaan" package for R statistical software. Internal consistency was estimated using Cronbach's alpha coefficient, and item sensitivity was assessed using the asymmetry and kurtosis coefficients. Empirical indices were considered: chi-square over degrees of freedom; comparative fit index; normed fit index; Tucker-Lewis index, and root mean square error of approximation; average extracted variance and composite reliability were used to assess convergent validity. Asymmetry and kurtosis were
